Hydraulic ram is pump which worked on the principle of
The hydraulic ram is a pump which raises water without any external power for its operation. One essential requirement for the satisfactory operation ofa hydraulic ram is the availability of a large quantity of water with a small positive head or height. This large quantity of water at a small height is sufficient to lift small quantity of water to a greater height. It works on the principle of Water Hammer.
